    Posted by Srinivas on April 11, 2023 at 5:22 am

    I am running one simulation on remote control aircraft. it run correctly.

    now I want to change the angle of Attack. I made change on 0/U folder according vector resolve.

    I have given 5, 10, 15, 18, AoA. all run correctly except 10 AoA. it gives following error.

    Hi,

    Your turbulence parameters diverges. I think that this AoA is a transition for separation if your simulation does not diverge for other AoA which is higher than 10.

    which solver do you use? Can you use AoA=5 results as initial for AoA =10 and then run and try.

    I am using simpleFoam as solver

    turbulenceProperties;- lomega sst

    I will try to use the result of 5 AoA as initial condition for 10 AoA. and will let you know

    I have run the command “mapFields ../5AoA  -sourceTime latestTime -consistent”

    it gives following error

    Hi Srinivas,

    I didnt understand why do try to map the results of AoA=5. Just take the final time step of AoA=5 folder. (lets say it is 1000/) rename it as 0 and open U file under of it and change the velocity as AoA=10 and then run again.

    Thats all

    As you said I have copy the 1000 and past in my 10 AoA and rename it 0 and change the AoA.

    and I  give decomposePar command. but gives following error.

    when I give the mapfield command it run successfully. but when i try to reconstruct the results it give the following error. I haver took the screenshot of the error.
